ALBERT S. TRASK, OF CONCORD, NEW HAMPSHIRE.

RADIATOR-VALVE Application filed February 21, 1907.

To all whom it may concern:

Be it known that I, ALBERT S. TRASK, a citizen of the United States, residing at Concord, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Radiator- Valves, of which the following is a specification.

My invention relates to a separating valve to be used for separating and cutting off a selected number of the units of a steam radiator in order to reduce the heating surface of the same.

The object of my invention is to provide a valve of this character which may be quickly and easily removed from the radiator, and which may be readily adjusted to cut off one or more of the units composing the radiator.

lVith this in view, my invention resides in the..,features of arrangement and construction hereinafter described and pointed out inthe accompanying drawings, in which,

Figure 1 is a horizontal section through the radiator and my improved valve, and Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Referring to the figures, 1, 2 and 3 respectively represent the units comprising the radiator, and provided with the abutting bosses 4, the units 1 and 2 of which are adapted to be connected by means of a thimble which engages in the threaded bore of the bosses 4; thereof. As shown in Fig. 1 particularly, the units 2 and 3 are connected in this manner, but,by a specially constructed thimble 5 having a contracted mouth 6, forming a seat for the valve 7 The valve 7 is provided with a screw threaded stem 8 which engages within the correspondingly threaded bore of the web 9 arranged within and preferably cast integral with the thimble 5. Valve 7 is further provided with a disk 10 of suitable material to insure solid seating upon the seat 6, and held in place by means of a nut 11.

A bushing 12 is threaded to screw within the boss 4 of the end unit 1 in place of the ordinary plug, and is provided with a threaded bore in which the threaded portion 13 of the operating rod 15 is adapted to work to seat and unseat valve 7. The bushing 12 is further provided with a contracted neck 14 through which projects the rod 15, and at the end of which is arranged a stufiing box 16.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Serial No. 358,710.

The operating rod 15 is provided on its outer end with a hand wheel 17, and on its inner end with socket 18, provided with a squared bore 19. The valve 7 is similarly provided with a square bored socket 20, cast integral with said valve. Between the sockets 1S and 20 I arrange a connection 21 in the form of an interchangeable bar square in cross section and adapted to fit snugly within the sockets 18 and 20 at its respective ends. It will thus be seen that I am able to apply the valve between any two of the units constituting the radiator and that I am also able to easily, cheaply and quickly compensate for the increase or decrease of the distance between the valve proper and its seat and the operating rod and hand wheel by means of the loose interchangeable connec tion above described. It will also be seen that I may easily and quickly remove the parts constituting my invention to readily get at the valve and its seat in order to change the position of the same within the radiator to cut off more or less of the heat radiating surface.

Having fully described my invention I claim:

A radiator comprising a plurality of unit sections, threaded connecting members for connecting said units, a selected one of said connecting members having a circular valve seat formed thereon and a web with a threaded bore, a valve provided with a threaded stem arranged through the threaded bore of the web of said connecting member, and adapted to be screwed upon the valve seat carried thereby, an operating bar threadedly arranged through the wall of said radiator and provided with a handle upon its outer end, said valve and said operating bar being provided with squared sockets, and a squared connecting rod arranged between said valve and said operating bar, and having its ends fitting loosely within said sockets to rotate said valve upon its seat when said operating handle is turned, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
